A Framework for Multicast and Quality based Forwarding in Manets

Keywords

Abstract

In this paper an experimental framework called WNet for
forwarding data frames in a wireless mobile ad hoc net
work is presented. The approach is based on the principles
of the OLSR protocol but is implemented as a forwarding
protocol on the MAC layer. One focus of the framework
is the support of efﬁcient multicast communication. The
design allows extensions concerning quality and priority
based forwarding, quality of service, congestion manage
ment, power awareness and security.
Since the framework is positioned on the MAC layer,
it has direct access to device parameters and can therefore
determine link and node attributes. These are used to cal
culate link qualities that inﬂuence the forwarding decision,
leading to a quality-based routing mechanism.
